Application led October 14, 1914. Serial No'. 866,598.

To all whom it may concern.'

Be it known that I, Mrs. NELLIE M. Mo- CAULEY, a citizen ofthe UnitedStates, re-

siding at Kalispell, in the county of Flatspraying insecticides or otherliquids.

One of the principal objects of the invention is to provide a spraywhich may utilize the water pressure in an ordinary garden hose or oneof a similar nature, in spraying the liquid Without resulting in themixture of the Water with the liquid.

` Another object of the invention is to provide a sprayer adapted to beplaced in a pipe or hose line and providing a collapsible containerdisposed. in a body or cylinder and communicating with the spray nozzle,one end of the container acting as a piston and adapted to be forcedalong the cylinder by Water pressure behind in order to collapse `thecontainer, lthus spraying the contents thereof out through the nozzle.

A further object is to provide a sprayer of the class described whichWill be extremely simple, durable, eiiicient in operation andinexpensive to manufacture.

With. these and other objects in viewV which will become apparent as thedescripf tlon proceeds, the lnvention resides 1n the construction,combina-tion and arrangement of parts, hereinafter more fully describedand claimed, and illustrated in the accompanying drawing, in which likecharacters of reference indicate like parts throughout the severalfigures, of Which- Figure l represents an elevatlonal view partly insection of a sprayer constructed according to my invention. Fig. 2 represents a longitudinal central sectional view taken therethrough. Fig. 3represents an elevational view of the container removed from thedevice.Fig. 4 represents a transf ceiving a flanged cover Both the cap 6 andcover 7 are provided centrally with threaded nipples 8. A sprayingnozzle 9 of the dravv-V any vvell known and suitable `construction maybe threaded onto the nipple carried by cover 7, anda garden hose orsimilar Water conduit (not shown) may be connected to the opposite endof the cylinder by means of the nipple carried by cap 6.

The container comprises a flexible cylindrical body 10 which may beformed of any flexible material impervious to the fluid to be sprayed.At one end of the body is disposed the flanged disk 11 towhich the bodyis securely fastened. The opposite end of the body is provided `With anexternally threaded collar l2. As indicated in Fig. 2 the container isdisposed longitudinally Within the cylinder, and the collar 12 isthreaded into the internally threaded-outer i i disk 11` in the oppositeend of the cylinder ad]acent cap 6, and the diameter of said disk issuch that the disk fits snugly lWithin the cylinder so as to form Iapiston capable of movement longitudinally of said cylinder.

Flexible container .10 is provided at suitably spaced points withencircling rings 14 secured to said container externally thereof andadapted to snuglyv t Within the cylinder 5. The rings are adapted to'prevent collapse of the container as the latter' isl being emptied. l

The container may be illed with the desired liquid and placed Within thecylinder, the latter of course being maintained in upright positionduring this process and the cover 7 may-be then threaded into place. Thehose may be connected to thenipple carried by cap 6. When the Water isturned on it will enter the cylinder behind the disk or piston 11, andthe Water pressure will `more said disk forwardly toward nozzle 9against the internal'pressure of the liquid contained in the collapsiblebody 10, thus forcing said liquid through the spraying nozzle. As thepiston moves forwardly in emptying the container the ringslfl willsupport the walls of body 10 and prevent them from collapsing, whichaction if not prevented mightresult in the blocking up orthe cuttingol"of communication to the spraying nozzle. The sprayer may beprovided witha handle 15, if so desired.

Such a structure as I have provided may A I be quickly attached to ordetached from an ordinary garden hose ora conduit of a similar natureand the Water pressure 'in the hose may be utilized in the manner setforth kin spraying the liquid from the container, Withoutl resulting inthe `mixture of the water with thev spr A aging liquid. Although I haveescribed the embodiment of my invention, `Inlay desire to make suchchanges inthe construction,

combination and arrangement of parts `r thereof as do not depart fromthe spirit of u prising. a cylinder, a cap disposed o n one' theinvention andthe scope of the ap` pended claims.

I claim.: I 1. 'A sprayer of the class describedjcomend of said cylinderfor closing. the same, a threaded nipple carried by said cap, wherebythesprayer may be attached to ahos'e, a

. cover removably dlsposed iipon the opposite endof the cylinder, athreaded nipple carried by said cover whereby a spraying nozzle may beconnected with the sprayer, a

' container dis losedjvvithin said cyllnder and including a exible'bodyportion, a'piston disposed at one end ofl sald container and acting as aclosure therefor, said piston being movable longitudinally of said c"linder, i

a collar carried by the opposite en .of the body portion and connectedlto the lcylinder internally thereof, and rings -car'ried in spacedrelation -by said flexible body portion and fitting within saidcylinder.

, 2..:'A device ofthe class described comthe'cylinder, a piston carriedl prising a cylinder closed at one end, means .at the closedy end,`ofthe cylinder for connccting the same with a fluid conduit, a coverremovably jsecured upon the opposite end of the cylinder, means carriedbysaid cover for connection witha sprayer nozzle, a v'c'.o'mpressible'container removably dispreferred lthe containerl 'tainer removablydisposed within the cylinder,'a piston secured tosaid container at oneend within the cylinder and adapted to be actuated upon entrance of thefluid into the cylinder, for contracting the container, means forpreventing collapse of the container andA means for establishingcommunication with said container at the end opposite the piston, with aspra er nozzle.

4. A device o the class described, coniprising a cylinder, a flexibleandcollapsible A container disposed therein and provided at one end-witha ring snugl engaging within the cylinder, the endv of t e containeradjacent the ring being open and being adapted to communicate with asprayer nozzle, a pisto'n connected to the opposite end of the containerand closing the sameand slidably engaging within the cylinder, ringscarried by the container in s aced relation and engaged within the cyinder andadav ted to' prevent collapse of the container an means wherebyfluid may` be forced into the cylinder against the. istonWherebyjocollapse or ejecting the contents Mns.
